The District of Columbia College Access Act of 1999 created a grant program with the purpose of expanding higher education choices for college-bound District of Columbia residents. This program, the D.C. Tuition Assistance Grant (TAG) Program, addressed the concern that D.C. students were at a disadvantage because the District of Columbia lacks a state university system. TAG allows undergraduates to attend eligible public universities and colleges nationwide at in-state tuition rates and provides smaller grants for students to attend private institutions in the District of Columbia and private historically black colleges and universities. The General Accounting Office (GAO) is required by the College Access Act to monitor the effects of the grant program on eligible students and assess the impact of the program on the University of the District of Columbia, which does not participate in TAG because in-state tuition is already available to D.C. residents. Data are from applicant data for the TAG program for 2000-2001 and a survey of parents (response rate, 42%) of 516 applicants who did not use the program. Twenty-one percent of grant-eligible applicants who did not use the funding may have faced other barriers to college access, especially college entrance examination score requirements. The grant can only be applied to tuition, and in many cases other college costs including room and board may have put institutions out of reach of applicants. Overall, the knowledge level about the TAG program appears adequate. The absence of minority outreach programs on the part of institutions contributes to the low use of TAG grants. The TAG program appears to have had little effect on enrollment at the University of the District of Columbia in its first year of operation. Overall, participating institutions report few problems with TAG participation. Five appendixes contain notes on the study scope and methodology, a list of participating colleges and universities, comments from the Mayor of the District of Columbia and the University of the District of Columbia, and a list of GAO contacts and staff.
